1966 film directed by Sergio Corbucci

High-tech robots equipped with state-of-the-art security devices have been recruited as the new mechanical "night watchmen" for the Park Plaza Mall. When a jolting bolt of lightning short-circuits the main computer control, the robots turn into "killbots" on the loose after unsuspecting shoppers!

When the quiet life of a beach bum is upended by dreadful news, he sets off for his childhood home to carry out an act of vengeance. However, he proves an inept assassin and finds himself in a brutal fight to protect his estranged family.
